Ooh, that's neat. I use a similar system, though mine permits several possible ways to encrypt a number and I usually pick an encryption with 5 or 6 digits. It doesn't require me to remember anything but the algorithm, so I don't feel comfortable with sharing it. I know it might be less secure than encrypting the pin with another pin, but I can't trust myself to remember any pin.
